You've just created a simple Play application providing a usable Play Autosource for ReactiveMongo.
With it, you can bootstrap in a few lines an automatic CRUD asynchronous datasource with REST endpoints back'ed on ReactiveMongo. It's quite useful to :

  • Kickstart an application and test your frontend
  • Build iteratively your models from blob to static (or just go on using blobs with some Json validations)
  • Expose your existing models as REST sources in a very few lines

The concept is explained more precisely in these articles:

Read these articles and look at code in app/Application.scala and conf/routes, it's quite explicit and provides everything to start.

To test it:

  1. Run a Mongo Server on your local computer
  2. Just run the application by launching classic sbt

Play-Autosource concept has been implemented for :

Maybe soon Activator's template for those Autosources...
